I thought I'd post a final update on my quest for the right power cord. Now that the CT5 has more than 1500 hours and I've updated the tubes, I decided to try a fully broken-in Python CX. It's a winner. It doesn't change the CT5's character;it just enhances what I love about it. There is a greater three-dimensionality to the presentation, deeper soundstage and greater control of the bass....and all of these things were great to begin with. I'd also like to note that through this quest I learned that power cords should ONLY be auditioned after equipment is fully broken in and that swapping a power cord from one piece of equipment to the other confuses matters. (I know..duh). With the Shunyata line I've noticed that the addition of each new power cord creates an experience that is greater than the sum of the system's parts. One PC is great, two are more than twice as good. Three is stunning. It's synergy, I guess. Of course, YMMV.
